Compress Text from StringBuilder to Gzip (BinData Output)

See more Gzip Examples

This example demonstrates how to use the CompressSb method to compress text stored in a StringBuilder into Gzip format.

The text is first converted to its byte representation using the specified character set (in this case, UTF-8). These bytes are then compressed, and the resulting Gzip data is written to a BinData object in memory.

This approach is useful when working with dynamically generated text that you want to compress without first writing it to a file. The example also shows how the compressed data can optionally be saved to a .gz file.

var success = false;

// This example demonstrates how to compress text contained in a StringBuilder
// into Gzip format, storing the compressed result in a BinData object.

var gzip = new CkGzip();
var sb = new CkStringBuilder();
var bd = new CkBinData();

// Add some text to the StringBuilder:
sb.Append("The quick brown fox jumps over the lazy dog.");

// Compress the text using UTF-8 encoding:
success = gzip.CompressSb(sb,"utf-8",bd);
if (success == false) {
    console.log(gzip.LastErrorText);
    return;
}

// The BinData now contains the Gzip-compressed bytes.
console.log("Compression successful.");
console.log("Compressed size (bytes): " + bd.NumBytes);

// (Optional) Save to a .gz file:
success = bd.WriteFile("text.gz");
if (success == false) {
    console.log(bd.LastErrorText);
    return;
}

console.log("Gzip file written to text.gz");
